The Stage-4 CMB experiment (CMB-S4) represents the next generation of CMB surveys [1]}. With planning underway, construction is slated for completion in 2029. CMB-S4 observatories will be located in both Chile and the South Pole, and will consist of an ultra deep survey, covering \(3\%\)  of the sky, and a deep and wide, high-resolution legacy survey covering over half the sky with a daily cadence; we use the latter here. The frequency range will be \(30 - 280\)  GHz, with a projected resolution of \(7.4^{\prime }\)  and \(0.9^{\prime }\)  at 30 and 280 GHz, respectively. For our simulations, we adopt a resolution of 2.2' at 93 GHz and a daily rms of 6 mJy, corresponding to an anticipated total noise depth of 1.97 \(\mu \) K-arcmin in this frequency band. The total survey duration is expected to be 7 years.
